Background:
There is concern about the increasing resistance of antibiotics to common bacteria. Delayed prescribing for respiratory tract infections is a strategy that may reduce the use of antibiotics.
Aim:
To systematically review controlled trials of delayed prescriptions to establish their capacity to reduce antibiotic intake.
Design Of Study:
A systematic review of the literature.
Setting:
Four studies were conducted in the United Kingdom and one in New Zealand.
Methods:
We searched MEDLINE from 1966 to April 2003, EMBASE, and the Cochrane Controlled Trials Register using the following terms: 'delayed', 'antibiotics', 'prescriptions', and 'back-up' (as in back-up prescription). We included controlled trials of studies in which the intervention was a delayed prescription compared to an immediate prescription for patients with upper respiratory tract infections. The studies were selected independently and the results compared. Disagreements were resolved by discussion. The data and quality of the studies were extracted and assessed independently by two of the authors.
Results:
Four randomised controlled trials and one before-after controlled trial contributed to the review. The relative risk in the randomised trials for lower antibiotic usage when a delayed prescription was given ranged from 0.54 for the common cold to 0.25 for otitis media.
Conclusion:
The consistent reduction in antibiotic usage in the five controlled trials included in this review suggests that delayed prescription is an effective means of reducing antibiotic usage for acute respiratory infections. The duration of delay for prescriptions ranged widely, from 1 to 7 days.
Insights
Delayed prescribing significantly reduces antibiotic use for respiratory infections. This strategy offers a practical approach to combat antibiotic resistance by lowering overall antibiotic consumption.
Area of Science:
- Infectious Diseases
- Pharmacology
- Public Health
Background:
- Growing concern over antibiotic resistance in common bacteria.
- Delayed prescribing as a strategy to mitigate antibiotic overuse in respiratory tract infections.
Discussion:
- Systematic review of controlled trials evaluating delayed prescriptions.
- Analysis of five studies from the UK and New Zealand.
- Inclusion criteria focused on delayed vs. immediate prescriptions for upper respiratory tract infections.
Key Insights:
- Delayed prescriptions consistently reduced antibiotic usage across included trials.
- Relative risk for lower antibiotic usage ranged from 0.54 (common cold) to 0.25 (otitis media).
- Effective reduction in antibiotic consumption for acute respiratory infections.
Outlook:
- Delayed prescription is an effective method for reducing antibiotic consumption.
- Prescription delay durations varied from 1 to 7 days.
- Potential for broader implementation in managing respiratory infections.
